Problems solved by technology
Although these methods can achieve the purpose of dimming and energy saving, there are the following problems: the control of the LED driver is complicated, the reliability is reduced, and the cost is high. However, the use of a separate control line will increase the wiring cost and increase the difficulty of energy-saving transformation of the old system.

Embodiment Construction
[0017] Such as figure 1 As shown, this embodiment has a host computer or a detection control system 1 capable of sensing the external environment or conditions, and the detection control system may include a detection device that senses the external environment such as a light sensor or a moving image sensor. The upper computer or the detection control system 1 may have a timing control program, or have intelligent detection equipment such as a light sensor, a moving image sensor, etc., and the detected information will be given according to the established program. The corresponding illumination control signal is transmitted through the communication interface 1- 1 is transmitted to the DC conversion device 2 on the power side. The DC conversion device on the power side is used to convert the AC power on the power side into a variable (0-400V) DC voltage. The DC voltage is transmitted to the remote LED constant current converter 4 through the cable 3 . The LED street lamp c...

The invention relates to an LED street lamp energy conversion and energy saving control device. The invention provides a device for adjusting brightness of LED street lamp according to road condition or command of a control system to prolong the service life of the LED street lamp and save energy to solve the technical problem. The technical scheme for solving the problem is as follows: the LED street lamp energy conversion and energy saving control device is provided with an upper computer capable of perceiving external environment or situation, or a detection control system, and is characterized in that the upper computer or the detection control system is connected with a power side DC conversion device via a communication port, the power side DC conversion device converts AC current power source at the power side into variable DC voltage, the DC voltage is transmitted to an LED constant current convertor at the remote end via a cable, the LED constant current convertor converts the transmitted variable DC power into DC constant current source needed by the LED street lamp group. The invention is applicable to illumination for urban roads, tunnels and other places.
Description
technical field [0001] The invention relates to the field of power supplies, in particular to a device for energy conversion and energy-saving control of LED street lamps. It is suitable for lighting in urban roads and tunnels and other occasions. Background technique [0002] Compared with conventional high-pressure sodium lamp street lamps, high-power LED street lamps have unique advantages such as high efficiency, safety, energy saving, environmental protection, long life, fast response, and high color rendering index, and can be widely used in lighting in urban roads and tunnels. [0003] At present, LED lighting technology is becoming more and more mature, and the efficacy of high-power LED light sources has reached about 1001m / W, which makes energy-saving transformation of urban street lamps and tunnel lighting possible. LED street lamps, especially high-power LED street lamps, are impacting the traditional street lamp market at a rapid speed. [0004] Compared with ...
